Keep up with the latest from the NFL rumor mill.

NFL free agency officially started Tuesday, March 10 at 4 p.m. ET. Teams didn't wait that long to get a head start on the offseason. General managers have busied themselves making roster cuts, negotiating with their own free agents and creating a little buzz on the rumor mill with trade talk.

The wildest news cycle in recent NFL history got underway with the completely unforeseen deal sending LeSean McCoy from the Eagles to the Bills in exchange for Kiko Alonso. It was off the races after that. The free agency tampering window, er, negotiating period, opened on Saturday, March 7, and the rumor mill has been cranking overtime since then, interrupted only by a long string of tweets from the various NFL insiders delivering shocking news about trades and signings and contracts and everything else that makes pro football's version of the hot stove so darn fun.

At any rate, it can be a lot to monitor when your Twitter feed is moving fast enough to generate electricity and one report would seemingly contradict the next one. That's why we have our handy rumor tracker, for you, the excited fan who only wants to see your team do something to make itself a little better next season. So follow along with the endless flow of information and speculation.
